INKING DEVICE.

Specification of Letters Patent. Patented Aug. 30, 1910.

Application filed January 31, 1905. Serial No. 243,506.

lowing is a speci cation.

My invention is especially designed for use with ink of the kindthat evaporates rapidly and my object is to provide an inking device of simple, durable and inexpensive construction in which ink is applied to an inking pad only during the time that the. inking pat is being used, to thereby avoid waste of ink when the inking pad is at rest, and my object is further to provide means for protecting the inking pad to avoid evaporation of the ink at all times except when the inking pad is in actual use.

A further object is to provide improved means for moving the inking pad to and from its inking position.

My invention consists in the construction,

arrangement and combination of the various parts of the inkin device, whereby the objects contemplate are attained, as hereinafter more fully set forth, pointed out in my claims and illustrated in the accon'ipanyiug drawings, in which Figure 1 shows a vertical sectional view of a frame containing a type wheel and embndying' my improved inking device, the. dotted lines show the inking device and connected parts in inking osition. Fig. 2 shows an enlarged detail sectional view through the ink well and connected parts with the inking pad'n eontact with the protecting pad, the dotted lines in said figure showing the position of the protecting pad when the inking pad is out of engagementwith it, and Fig. 3 shows a detail perspect-ive view of the ink well and connected parts.

Referrin to the accompanying drawings, I have used the reference-numeral to indicate the frame provided with an opening 1.1 througlnwhich the inking pad is projected to en age the face of the type wheel 12. The in% well and inking pad are carried upon the outer ends of two parallel arms 13, which aims are provided with curved inner end portions 14 passed around a stationary rod 15 and on able of a rotary movement on said rod an also capable of sliding forwardly and rearwa'rdly'aslight distance on said rod, one of said arms 13 is provided with a toothed portion 16 which toothed portion is in mesh with a lever 17 fulcrumed to a pin 18 belowit and formed with teeth 19 in mesh with the teeth 16. The lower end of the lever 17 is provided with a roller 20, for purposes hereinafter made clear, and a contractible coil spring 21 is connected to the lower end of the lever 17 and to a in 22 on the machine frame to normally ho d the lever 17 in the position shown in solid lines shown' in Fig. 1. Below the lever 17 I have pivotally supported an arm 23 on the journal 24. Pivoted to the outer end of the arm 23 is a cam 25 formed with a rounded surface 26 and a shoulder 27 designed to engage the roller 20. I have provided for yicldingly holding the cam 25 upwardly by means of an extensible coil spring 28 mounted on alug-29 on the arm 23 and engaging a lug 30 on the cam 25. Pivoted to the frame 10 is an operating lever 31 formed with a handle 32 on which is a platen 33. A link.3-it is pivoted to the lever 31 and to the arm 23. The operation of this portion of my improvement is as follows: Assuming the parts to be in the position shown in solid lines in Fig. 1 and assuming that the operator presses the handle 32 toward the type wheel 12, then the link 34 will draw the arm 23 downwardly, which will move the cam 25 forward-1y. The spring 28 will hold the cam in engagement with the roller 20 throughout a part of its movement, but when the roller 20 has moved to the position shown by dotted lines in said figure, it will pass'out of the: shoulder 27 and its spring 21 will return it quickly to the position shown in solid lines. While the lever 27 is being moved from the position shown in solid lines to the position shown in dotted lines. the arms 13 will be moved downwardly until they strike upon the sleeve 35 on the rod 36 whereupon their downward movement.- will be limited and a further movement of the lever 17 will movethem inwardly, so that the printing block will pass through the opening 11 of the frame and engage the face of the type wheel. As soon, however, as the roller 27 slides out of the shoulder of the cam, then the spring 21 will immediately force the arms 23 outwardly so that the printing block passes out of the opening 11 and then the arms 1.3

will be rapidly elevated to the position shown in solid lines.

in use the operating lever 31 moves from the position shown in solid lines to the position shown in dotted lines during the time that the arms l3'move downwardly and inwardly and then the arms 13 are thrown upwardly by their operating springs while the lever 32 completes its printing move ment.

The ends of the arms 13 are connected by a plate 37. The ink'well 38 is supported in the rear of the plate 37 and between the arms 13 and is provided with an over-flow opening 39 in its inner face near its upper end and also with a filling opening in its top, in which the screw 40 is placed to close the opening. Secured to the inner face of the ink well is an inking pad 41 made of absorbent material suitable for inking type.

The ink protecting device comprises a pad holder 42 pivoted at 43 and having a forwardly projecting arm 44;. A pad 45 of absorbent material is mounted in its forward face T he said device normally hangs on its pivot 43 in position where its arm 41 is extended in front of the frame and in the path of the plate 37 and its parts are so con structed and arranged that when the arms 13 move upwardly, the plate 37 will strike the arm 44 and limit the upward movement. of the arms 13 and throw the pad 45 into position in engagement with the pad 41.

The springing means that hold the arrhs 13 upwardly will operate to hold these pads 41 and 4:5 firmly in engagement. In Fig. 2 of the drawings, the dotted line 616 indicates the level of the ink within the well when at its maximum, that is to say, the level of the ink is always below the opening 39. Hence there is no direct flow from the ink well to the inking pad, However, when the ink well is being moved from its position at rest to printing position and back again, the ink in the well will be agitated to such an extent that a slight quantity of it will pass through the opening 39 to the inking pad. Hence when the inking device is being constantly used, a relatively large quantity of ink will be distributed, but when it is not frequently used, the ink will not be distributed. When the inking device is in its position at rest, the surfaces of the pads ll and 45 will be in close contact and no air can enter between them. Hence, there will be little or no evaporation of the ink. Furthermore, the pad 45 will absorb any excessive ink upon the pad 41 and, therefore, thepad/ll will at all times be in proper con dition as regards the quantity of ink thereon for printing purposes and this is all done automatically withoulithe attention of the opripator so long as any ink remains in the We Having thus described my invention, what cease?
